Description

This vibrant and tangy Green Beans with Mustard Butter Sauce recipe features fresh green beans cooked to crisp-tender perfection and tossed in a flavorful sauce made from coarse grain mustard, Dijon mustard, lemon juice, and melted butter. It’s a quick, simple side dish that adds a bright, zesty touch to any meal and can be easily adapted for vegan diets by substituting butter with olive oil.


Ingredients

Scale

Green Beans

  • 1 pound fresh green beans, trimmed

Mustard Butter Sauce

  • 1 tablespoon coarse grain mustard
  • ½ tablespoon Dijon mustard
  • ¼ teaspoon kosher salt
  • ⅛ teaspoon black pepper
  • Juice of ½ lemon
  • 2 tablespoons unsalted butter, melted


Instructions

  1. Cook the Green Beans: Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for about 5 minutes until they reach a crisp-tender texture. If you prefer softer green beans, extend cooking time by a few minutes.
  2. Prepare the Mustard Butter Sauce: While the green beans cook, combine the coarse grain mustard, Dijon mustard, kosher salt, black pepper, lemon juice, and melted butter in a medium bowl. Whisk them together until smooth and well incorporated.
  3. Drain and Toss: Drain the cooked green beans thoroughly and immediately transfer them to the bowl with the mustard butter sauce. Toss gently but thoroughly so that all beans are evenly coated with the sauce.
  4. Serve: Serve the green beans immediately to enjoy the fresh, tangy flavors at their best. This dish pairs wonderfully with roasted meats or as part of a fresh vegetarian spread.

Notes

  • Butter: For a vegan version or lighter alternative, substitute the unsalted butter with olive oil to create a vinaigrette-style sauce.
  • Mustard: Whole grain mustard delivers great texture and flavor, but if unavailable, you can use all Dijon mustard instead for a smooth, slightly milder taste.
